Friday April 15
The day shift began with Operations monitoring store 4098, the Recyclerstash, and the Antiproton Source (Pbar) stack, and with experts investigating a magnet problem in the P1 or P2 transfer line.

Operations terminated store 4098 around 11:33 AM. Operations then began preparing the Tevatron (TeV) for an access into F sector to inspect the P1 and P2 transfer lines, which are in F0 and F1 respectively.

The TeV tunnel accesses began at 12:28 PM.

Experts in the P2 transfer line reported at 2:23 PM finding a quadrupole magnet with a turn-to-turn short. They began the process of replacing the magnet.

The Plan for Monday
The plan for today is to terminate store 4100 around 11 AM. The Run Coordinator will allow TeV experts to install some new octupole curves and then test them with a study period. Operations will establish a new store later this afternoon.
